A while back I made this steel recurve crossbow. Always wanted to make a crossbow for airsoft, so I went ahead and did it. It uses a 20 pound (ish) draw steel bow with wooden siyahs to decrease weight and shorten the working length. Sights are windage and elevation adjustable, safety optional, and bow can be taken off the stock for storage. I do not own a chrony, but I'd say it shoots 140-180 FPS with some .30 gram bbs. It's no speed demon, but that's because it's supposed to simulate a crossbow.

I'm very proud of it, and enjoy how it came out. Hope you guys like it!

(BTW, I am aware shooting airsoft bbs can be considered dryfiring a crossbow. That is an issue with 150 pound fiberglass and wood bows, but with a steel bow that's only 20 pounds, there is no real issue, it can take it. I am also aware that I can convert the crossbow to a spring-piston design. I don't see the point in that, it wouldn't be a true crossbow anymore. Thanks for understanding.)

Late reply but looking back on this yeah I whole heartedly agree. Issue with crossbows is that high power means a heavy projectile is used to that there is enough energy transfer. Airsoft bbs weigh nothing, and if you make a bow too powerful it will either break or vibrate violently. Either way, definitely nothing more than a novelty.
